"Never will the barking of dogs deter the Nightingale from warbling its melodies."

"Say: O people, do ye imagine that, after rejecting the One through Whom the religions of the world have been made manifest, ye still bear allegiance to the Faith of God? By the righteousness of God! Ye are accounted among the inmates of the Fire. Thus hath the decree been recorded in the Tablets by the Pen of God. Say: Never will the barking of dogs deter the Nightingale from warbling its melodies. Ponder awhile that perchance ye may discover a path leading to the Eternal Truth."

-Bahá'u'lláh, The Summons of the Lord of Hosts, Súriy-i-Ra’ís, p. 156
